Toggle Navigation Panel button throwing errors and not working in maximized image

[Vass_Dts]

When an image/map is maximized (regardless of steps), the Toggle Navigation Panel button does not work, and throws the following error whenever pressed:

It functions normally if the images is not maximized (is in windowed mode).

Even if the panel has been activated while the image is windowed, it disappears when the image is maximized.

I just pushed a fix for the navigation panel toggle button script error when the image is set to a background panel. Please run a new Check for Updates, and try again.
